METHOD OF MANUFACTURING PULL MATCH PACKAGES AND APPARATUS THEREFOR Filed June 29, 1936 INVENTOR- ATTORNEYS Patented Sept. 7, 1937 UNITED STATES PATENT OFFIQE METHOD OF MANUFACTURING PULL MATCH PACKAGES AND APPARATUS THEREFOR ration of Delaware Application June 29, 1936, Serial No. 87,819 In Germany March 14, 1934 13 Claims.

The invention relates to the manufacture of pull match'packages in which the match strips lie between cover strips corrugated to form pockets for the matches.

In manufacturing such packages a match strip is fed between two cover strips, which are joined together and cut into the proper lengths.

According to my invention the member feeding the match strip makes a pause after each insertion of a length of match strip for one package.

The invention includes apparatus embodying this feature, and other features which will be pointed out hereinafter.

An example of such apparatus is shown in the accompanying drawing, in which Fig. 1 is an elevation of a portion thereof,

Fig. 2 a plan view, and

Fig. 3 a view from the left of Fig. 1, with parts removed. I

In the machine shown there are three rolls I, 2, 3 mounted in a frame 4. A toothed wheel 5 fixed to the roll 2 meshes with a toothed wheel 6 fixed to the shaft of the roll 3. The rolls 1 and 2 have rings of teeth 8 and 1 respectively, for imparting a corrugated shape to a strip of cardboard or the like fed between them as indicated at a. The cardboard strip after leaving the bight of rollers I and 2 is entrained about the left-hand side of roller 2 and threaded between rollers 2 and 3. As shown in Fig. 3 the teeth are divided into groups of five, separated by much wider teeth, marked I in the case of the roll 2. A cam ring II] with noses 9 is fixed to the roll 2, which is driven.

The roll 3 serves as a feed roller for the match strip b and is mounted on a lever ll pivoted at 12 to the frame 4. The roll 3 has two rings of teeth 3 engaging the matches, and the lever It carries a pawl l3 engaging the noses 9. On the lever ll there is a bed [4 for a slide IS, on which a cutter wheel [6 is mounted, the slide being adjustable in relation to the roll 3 by means of a screw l'l. Flanges It on the lever prevent the matches from dropping away from the teeth 3 The cutter wheel I6 is driven by a pinion l9 meshing with the wheel 6.

The cutter wheel cuts the web of the match strip at regular intervals, so as to divide it into sections, each with five matches, and the sections are carried by the roll 3 to position 0, where the matches are laid in the corrugations of the cover strip. Each time a section has been so placed a nose 9 of the cam It) strikes the pawl l3 so that the lever II is lifted and the wheels 5 and 6 are disengaged from each other. Rotation of the roll 3 then stops, due to friction or to a brake 29 applied as to the shaft 20, and then the pawl becomes disengaged from the cam nose and the wheels 5 and 6 are brought into engagement 5 again. In the example shown the noses 9 are of such width that the re-engagement of the wheels 5 and 6 takes place when the wheel 5 has rotated through an are equal to the circumferential width of one tooth. D

The pauses which occur in the feed of the matches to the cover strips have the eifect of placing the sections of match strip between the covers with intervals between them.

The downward movement of the lever It may be assisted by a spring, and is 'limited by a stop not shown, so that the wheels 5 and 6 enter into mesh smoothly.

The pitch of the teeth of the wheels 5, 6 corresponds with that of the wheels I, 3 and also with the spacing of the matches.

The noses 9 are preferably made of harder metal than the pawl [53, so that when wear occurs it can easily be corrected by renewing the pawl. The cam ring In is adjustable, as shown at 38, and pawl I3 is adjustable, as indicated at 3!, to enable the requisite precision to be obtained.

The second cover strip 32, which may be smooth, passes round the roll 3 and is laid against the match strip b. It travels between the rings of teeth 3 and is stuck to the crest of the corrugations of the other cover strip. It may, alternatively, be fed from the right by the roll 3, as viewed in Fig. 1, an additional roll serving to press it against the cover strip with the matches already laid thereon.

What I claim as my invention and desire to secure by Letters Patent of the United States 1. Apparatus for the purpose set forth, comprising in combination a roll for continuously feeding a corrugated cover strip, a roll for feed-- ing a series of matches to said cover strip, a lever carrying said second mentioned roll, a pinion fixed to said second mentioned roll, a toothed driving wheel fixed to said first mentioned roll and normally engaged by said pinion to drive said rolls and feed said corrugated cover strip and said series of matches together at the same rates of speed, and a cam whereby said lever is rocked at intervals for disengaging said pinion from said toothed wheel to interrupt the feed of said series of matches while continuing the feed of said corrugated cover strip.

2. Apparatus as claimed in claim 1, including a brake for stopping at intervals the feed of the matches.

3. Apparatus as claimed in claim 1, including a cutter for cutting into sections a match strip fed towards the cover strip.
